please answer this question with proper explanation

Answer 1

Answer:

8/5. mark it as brainliest.

Step-by-step explanation:

The ball picked = red + green= 1/5+1/3=8/15

p(E)= (8/15)/3=8/5

Answer 2

Answer:

8/15

explanation:

first take the LCM of the denominator

we will get the LCM equal to 15

therefore 1/5=3/15(red)

1/3=5/15(green)

7/15(blue)

the probability that a boy Pick at random is red or green colour = probability of red + probability of green

=3/15+5/15

=8/15
