Some1 owns a chocolate shop. A popular product is a box of 40chocs. 5 of which are nuts.
if u pick 2 out, randomly, What is the probability that both chocolates are nuts
Pr = 5/40 * 4/39
check my thinking.
Your thinking is correct. To find the probability that both chocolates picked are nuts, you need to multiply the probability of picking a nut chocolate on the first pick by the probability of picking a nut chocolate on the second pick.
The first pick has a probability of 5 out of 40, since there are 5 nut chocolates out of a total of 40 chocolates. After one nut chocolate is picked, there are 4 nut chocolates left out of the remaining 39 chocolates for the second pick.
Therefore, the probability of picking two nut chocolates in a row is:
Pr = (5/40) * (4/39) = 20/1560 = 1/78
So, there is a 1 in 78 chance that both chocolates picked will be nuts.
