Answer: 0.07
Step-by-step explanation: Since it is a binomial experiment , we will use the formula:
n C r [tex]p^{r}[/tex][tex]q^{n-r}[/tex]
p = 0.35
q = 1 - 0.35 = 0.65
n is the number of trials = 7
r = 3
substituting into the formula, we have
7 C 3 ([tex]0.35^{3}[/tex][tex]0.65^{7}[/tex]
= 35([tex]0.35^{3}[/tex][tex]0.65^{7}[/tex]
=0.0736
to the nearest tenth
= 0.07
