Question

The probability that a red block is selected from a bucket is

3/8, and the probability that a blue block is selected is 2/8.
What is the probability that a red block or a blue block is
selected?
a) 1
b) 1/2
c) 5/8
d) 6/8

Answer 1

5/8

Explanation:

The probability of a red block shows 3/8. This means there are 8 blocks total and only 3 of them are red.

The probability of a blue block shows 2/8. Again there are 8 total blocks and only 2 are blue.

So the total number of blocks remains the same....8

The total of red and blue blocks is 3 + 2 = 5

So the probability would be 5/8

Answer 2

5/8

Explanation:

Since we don't know what the other color (s) are, all we need to do to determine the probability is add the two fractions, and that is your probability.
