The right answer gets brainlist

5%

Step-by-step explanation:

Boys are represented by h

We are looking for 4 boys so we want 4 h's

Of the 20 outcomes, there is only 1 with 4 h's

The experimental probability is  number of outcomes with 4's over the total number of outcomes

P() =1/20

Changing this to a percent is  1/20 *5/5 = 5/100 = 5%

5%

Step-by-step explanation:

P(H,H,H,H) = 1/20 = 0.05

0.05 × 100 = 5%
