Question

Answer 1

Respuesta:

4 coins are tossed, what is the probability that 2 heads will come up? It can be seen that there are 6 of those 16 that have 2 faces. 37.5% of the time there will be 2 heads, and 62.5% of the time the number of heads will be different from two. Another way to do this is to calculate the permutations with repetition.
