Question

What is the combined probability of getting a heads when flipping a coin and an even number when spinning a spinner with 5 equal parts numbered 1 to 5?A.1/5B.1/2C.2/5D.3/10

Answer 1

The probability of the coin and the spinner are independent, so the combined probability will be the product of the probability of each outcome.

The first outcome is heads in a coin flip, so the first probability is 1/2.

The first outcome is getting an even number out of the 1 to 5 numbers. We have only 2 and 4 as even numbers out of the total 5, so the probability is 2/5.

The combined probability is then:

`P=(1)/(2)\cdot(2)/(5)=(1)/(5)`

So, the combined probability is 1/5.
