Answer:

a.) P(HH|C)=2/5

Explanation:

Given following:

P(HH) = 7

P(C) = 10

P(HH ∩ C) = 4

P(HH ∪ C) = 13

Solving steps:

$\sf P(HH|C) = \dfrac{P(HH \cap C) }{P(C)}$

$\sf P(HH|C) = \dfrac{4 }{10}$

$\sf P(HH|C) = \dfrac{2 }{5}$

Answer:

38%

Step-by-step explanation:

Change $\frac{7}{25}$ to a percent, that is

$\frac{7}{25}$ × 100% = 0.28 × 100% = 28%

Then 34% + 28% = 62% ← go by bus or car, leaving

100% - 62% = 38% walking to school
