Question

Raymond places four colored blocks in a bag. The colors are red, blue, yellow and green. Without looking, he reaches into the bag andpulls one block out.What is the probability that the block he pulls out will be yellow?A. 1/4. B.1/3. C.3/1. D.4/1

Answer 1

Given:

Total number of colored blocks in the bag = 4

Given that Raymond picks one block out without looking(randomly), let's find the probability it is a yellow block.

Probablity can be said to be the likelihood of the occurence of an event.

Given:

Number of yellow blocks = 1

To find the probability that the blocks he pulls out will be a yellow block, apply the formula below:

`P(\text{yellow)}=\frac{\text{Number of yellow blocks}}{Total\text{ number of blocks}}`

Thus, we have:

`P(\text{yellow)}=(1)/(4)`

Therefore, the probability thatvthe block he pulls out will be yellow is ¼

ANSWER:

`A\text{. }(1)/(4)`
