Question

suppose the probability of someone having a reaction to a medication is 0.025 what is the probability of two out of tree people having a reaction?

Answer 1

Given :

The probability of someone having a reaction to a medication is 0.025 .

To Find :

The probability of two out of tree people having a reaction.

Solution :

Let, P is the probability of two out of tree people having a reaction.

So, P = ( first had reaction ) × ( second had reaction ) × ( third do not had reaction )

P = 0.025 × 0.025 × ( 1 - 0.025 )

P = 0.00061

Hence, this is the required solution.
