Question

A bag contains 35 red​ blocks, 48 greeen blocks, 23 yellow blocks, and 19 purple blocks, You pick one block from the bag at random. Find the indicated theoretical probability.

​P(yellow or green​)

Answer 1

= 71/(71+54) = 71/125 = 568/1000= 56.8% chance of yellow or green

if cop cars are around, not a good idea to possibly run a red light, hoping it's green or yellow

Answer 2

Probability is desired/total.

"Or" probability is add.

Total is 125.

Yellow or Green is 23 + 48 = 71.

P(Y or G) = 71/125
