How many outcomes are there with tossing a coin and rolling a number cube?
List all the possible outcomes for each experiment. A standard number cube is rolled, then a coin is flipped. Four coins are flipped. The two spinners are spun….

What is the probability of rolling an odd number on a number cube and tossing tails on a coin?
So the answer is 1/4. You can use a tree to better understand probabilities. The possible outcomes are (H,1),(H,3) and (H,5) where H is the head when a coin is tossed and 1,3 and 5 are the odd outcomes of rolling a cube. Hence, required probability is 1/2 x 1/6 + 1/2 x 1/6 + 1/2 x 1/6 = 1/4.
What is the probability of flipping a coin and getting heads then rolling the dice and getting an odd number?
The answer is 14. My reasoning is that rolling an odd number is 12, and tossing a coin on heads is 12. So 0.5×0.5 = 14.
What is the probability of flipping a coin and getting a tails and rolling a number cube and getting a 6?
1/12
Answer: The probability of getting a tail and a six when a coin is tossed and a cube is rolled is 1/12. Let’s find the probability. Given that both the events occured simultaneously.
How many possible outcomes are there if you toss 2 coins?
four possible outcomes
Outcome – Flipping Two Coins. In an experiment of flipping two coins, there are four possible outcomes.
What is the probability of rolling a 3 or tossing heads on a coin?
1/4
This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin. Thus there are only 4 outcomes which have three heads. The probability is 4/16 = 1/4.
What is the probability of flipping heads and rolling a one?
Since there are 4 possible outcomes with one head only, the probability is 4/16 = 1/4.
What is the probability of tossing heads and rolling an even number?
Let p1 denote the probability of a head when the coin is flipped and p2 denote the probability of an even number when a dice is tossed. The outcomes being independent, probability of rolling a head and an even number= p1*p2. When the coin and dice are unbiased, p1=p2= 1/2. Hence required answer is 1/4.
What is the probability of flipping tails and rolling a 5?
Assuming the coin is fair, the probability of tossing tails is 12 (because there are two, equally likely options). Therefore, to get the probability of rolling a 5 AND tossing tails, you multiply (16) by (12) , and get the answer (112) .
How many possible outcomes are there in tossing 3 coins?
The sample space of a sequence of three fair coin flips is all 23 possible sequences of outcomes: {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}.
