Answer:
P(green or orange) = 4/7
Step-by-step explanation:
We need to know how many tennis balls there are
total = 15 yellow+ 5 orange+ 15 green
= 35 balls
Probability of green or orange tennis ball is the sum of the green and orange tennis balls over the total balls
P(green or orange) = (green + orange)/total
= (15+5)/35
=20/35
=4/7
Answer:
Green= 15/35 0r 3/7 Orange= 5/35 0r 1/7 Both= 20/35 or 4/7
Step-by-step explanation:
Add up all the balls = 35
Add the orange and green balls = 20
Put into fraction.
20 balls out of the 35.
20/35 or 4/7
Hope this helps.
