Why is it wrong to say that in a toss of a coin the probability of getting a head is 1 2?

Hence, when we say that the probability of getting a heads is 1/2, what it actually means — according to the frequentist approach — is that as you keep on tossing your coin (the more number of times the better), the ratio of the number of times you get a head to the total number of tosses will approach the value of 1/2 …

What is the probability that there will be 53 Sundays in a leap year?

The probability that a leap year selected at random contains 53 Sunday is (1)7/366 (2)28/183 (3) 1/7 (4) 2/7. We know that a leap year has 366 days. So, we have 52 weeks and 2 days. Hence, a leap year has 52 Sundays.

What is the probability of getting a total of 7 or 11 when a pair of fair dice are tossed?

8/36 or 2/9, 22.22\%. Nearly a 1 in 4 chance of getting 7 or 11.

How do you write at least one in math?

2 Answers

1. The existential quantifier “∃x.
2. since “at least one” is the conventional mathematical meaning of “some”+singular noun.
3. Note that whereas one occasionally sees people abbreviate, for example, “f(x)>0 for all x” as “f(x)>0 ∀x”, this heinous abuse of symbolism is rare for the existential quantifier.

What is the probability of B getting the first chance?

A’s chance of winning on the first toss is 1/2. If A tosses a tails (probability 1/2), there’s a 1/2 probability that B will get a heads. So B’s probability of winning on his first toss is 1/2 * 1/2, or 1/4.

What are the odds of 10 heads in a row?

a 1/1024 chance
Junho: According to probability, there is a 1/1024 chance of getting 10 consecutive heads (in a run of 10 flips in a row).

What is the probability of passing at least one subject?

Hence, the passing of both would be 3/5 * 1/3=1/5. The probability of passing at least one subject would be 1 minus the probability that he would fail both. Such a probability would be 2/5 * 2/3 = 4/15. Hence, the probability of passing at least one would be 11/15.

What is the probability of passing neither statistics nor accounting?

Probability of passing neither statistics nor accounting = 0.15625 ~ 15.6\%. What is the probability that a student will pass at least one of the subjects if in English the probability is .60 and in science is .45, then his probability to pass both subject is .40?

What is the probability of passing the exams in English and Hindi?

Ex 16.3, 20 The probability that a student will pass the final examination in both English and Hindi is 0.5 and the probability of passing neither is 0.1. If the probability of passing the English examination is 0.75, what is the probability of passing the Hindi examination?

What is the probability that 2 chips are bad?

(Example for one of the terms: to find the probability that exactly 2 chips are bad, keep in mind that any 2 of the 4 chips can be bad, and so multiplication by (4 choose 2) = 6 is needed.) Of course, it is much easier to just find 1 – P (no chips are bad) = 1 – (0.98)^4 than to go through all the calculations for 1, 2, 3, and 4 bad chips.
