Question

On Eduardo's workbench are the following

paint cans.
• 3 cans of red paint
• 5 cans of blue paint
• 8 cans of green paint
• 4 cans of yellow paint
Eduardo will randomly choose one can of
paint. What is the probability that he will
choose a can of red paint or a can of blue
paint? (71A, 7.1B, 7.1F)

Answer 1

Answer: 2/5

Explanation:

Number of cans of red paint = 3

Number of cans of blue paint = 5

Number of cans of green paint = 8

Number of cans of yellow paint = 4

Total number of cans of paint = 20

The probability that Eduardo will

choose a can of red paint or a can of blue will be:

= P(red) + P(blue)

= 3/20 + 5/20

= 8/20

= 2/5

The probability is 2/5.
