What is the probability of drawing a black sock?

There is a 12 out of 24 chance that the first sock you pick is black, because there are 12 black socks out of the total 24 socks. Simplified, this is a 1 out of 2, or 50 percent, probability.

What is the probability of at least two coins landing on heads?

0.25
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.

What is the probability that at least two of the coins will be tails?

All the eight outcomes are equally likely to occur. In four out of eight of them (the ones that are colored red), we see at least two tails. Therefore, the probability of getting at least two tails is 48=0.5.

What is the probability of two socks of the same color?

When two socks are pulled out randomly, the possibility that they are of same color would be when we pull out BB or W W. the probability of pulling out one black sock is 8 16 and pulling out another black will be 7 15, as we are left with 15 socks with 7 black socks.

What do B and W mean when pulling out a sock?

Let B denote pulling out a black sock and W denote pulling out a white sock from the drawer. When two socks are pulled out randomly, the possibility that they are of same color would be when we pull out BB or W W.

What is the probability that the first and second will be blue?

So, the probability that the first will be blue is 6/10 = 3/5. Assuming the first s blue, that would leave 5 blue and the other 4 non-blue, so the probability that the second will be blue is 5/ (5+4) = 5/9. Therefore, the probability that both will be is the multiplication of the two: 3/5 X 5/9 = 15/45.
