Question

What is the probability of both coins landing on heads?

Answer 1

Solution:

There are two coins, both have one head and one tail. So, the probability of one coin on head is 1/2. Two evens must be happened in the same time for our case. For that we need to multiply their probabilities landing on head.

$P(AB)=P(A)P(B)=\frac{1}{2}\times\frac{1}{2}=\frac{1}{4}.$

Answer:

$P(AB)=\frac{1}{4}.$
