Question

The probability that Adrian has Mr. Muller as his science teacher next year is 0.25,

and the probability that he has Mrs. Waugh as his math teacher next year is 0.5.
He wants to determine the probability that he has both Mr. Muller and Mrs. Waugh as teachers next year and needs to design a simulation to help him calculate this probability. He has the spinner shown below and a number cube.

Which of the following simulations could Adrian use to help him determine the probability that he has both Mr. Muller and Mrs. Waugh as teachers next year?
Responses

getting a 1 on the spinner and rolling a number greater than 4
on the number cube
getting a 2 on the spinner and rolling an odd number on the number cube

getting a 3 on the spinner and rolling an even number on the number cube

getting a 2 on the spinner and rolling a prime number on the number cube

Answer 1

the answer would be spinning a 3 and getting an even number on the number cube. read why below!

Explanation:

the guy is right

Answer 2

the answer would be spinning a 3 and getting an even number on the number cube. read why below!

Explanation:

because the spinner presents three options (two 2s, a 3 and a 1), there is a 50% chance that he will spin a 2. the spinner has to be able to represent his chances of having mr. muller as his science teacher though, because there is only a 25% chance that he will spin a 1 or a 3.

the number cube might be difficult to understand, but because there are 3 even numbers and 3 odd numbers, the chances of rolling an even or an odd number are equal: 50/50 chance, which represents his chances of having mrs. waugh as a teacher.

i hope that this helped!
