Question

Suppose a 250-brick set of Braille Bricks includes 50 pieces of each of five colors: red, yellow, green, blue and orange. If Kevin chooses one piece of lego at random, what is the probability that he chooses a red or a yellow piece? Write your answer in simplest fraction form.

Answer 1

Answer: 2/5

Step-by-step explanation:

Number of red bricks = 50

Number of yellow bricks = 50

Number of green bricks = 50

Number of blue bricks = 50

Number of orange bricks = 50

Total number of bricks = 250

The probability of choosing a red piece is 50/250 = 1/5. Also, the probability of choosing a yellow piece is also 1/5.

Therefore, the probability that he chooses a red or a yellow piece will be:

= P(red) + P(yellow)

= 1/5 + 1/5

= 2/5
