Answer: 0.07

Step-by-step explanation: Since it is a binomial experiment , we will use the formula:

n C r p^{r}q^{n-r}

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 (0.35^{3}0.65^{7}

= 35(0.35^{3}0.65^{7}

=0.0736

to the nearest tenth

= 0.07
