zlopas [31]

Answer:

Number of cars needed for the trip = 11

Step-by-step explanation:

Given that:

Number of children = 40

Number of adults = 12

Total number = 40 + 12 = 52 people

Each car can hold 5 people.

Number of cars = $\frac{52}{5}$

Number of cars = 10.4

Rounding off to next whole number as one car can hold a maximum of 5 people.

Number of cars = 11

Hence,

Number of cars needed for the trip = 11

3) 0.30

The probability a randomly selected student plays a sport given they work part time = 0.30

Step-by-step explanation:

Step(i):-

Given 'A' plays a sport

B work part time

Given P(A) = 0.48

P(B) = 0.40

P(A∩B) =0.12

P(A∪B)¹ =0.24

Step(ii):-

By using conditional probability

$P(B/A) = \frac{P(BnA}{P(A)}$

and similarly $P(A/B) = \frac{P(AnB}{P(B)}$

The probability a randomly selected student plays a sport given they work part time

Now $P(A/B) = \frac{P(AnB}{P(B)}$

$P(A/B) = \frac{0.12}{0.40}= 0.30$

Final answer:-

The probability a randomly selected student plays a sport given they work part time = 0.30
