Write your answer as a fraction or as a whole or mixed number.

Answer 1

Answer:

$= { \tt{ \frac{4}{5} \times \frac{2}{3} }} \\ \\ = { \tt{ \frac{8}{15} }}$

The fraction of students who do long jump event on the track team is 8/15

Answer 2

• P(A)=2/3
• P(B)=4/5

Fraction of students doing long jump

P(A,B)

• P(A)×P(B)
• 2/3×4/5
• 8/15
