Question

Two wheels of chance are spun. the first is marked 1, 2, 3, 4 and the second is 1, 2, 3 On both wheels each number is equally likely, how many ways can at least one is odd be obtained?

Answer 1

Answer:

There are 10 ways to obtain at least one odd number when spinning the two wheels of chance.

Step-by-step explanation:

To find the number of ways to obtain at least one odd number when spinning the two wheels of chance, we can first find the total number of outcomes and then subtract the number of outcomes where both numbers are even.

Total number of outcomes when spinning both wheels = (Number of outcomes on the first wheel) * (Number of outcomes on the the second wheel)

= 4 * 3

= 12

Now, let's find the number of outcomes where both numbers are even:

The even numbers on the first wheel are 2 and 4.

The even numbers on the second wheel are 2.

So, the number of outcomes where both numbers are even = (Number of even outcomes on first wheel) * (Number of even outcomes on the second wheel)

= 2 * 1

= 2

Now, let's subtract the number of outcomes where both numbers are even from the total number of outcomes to find the number of outcomes where at least one number is odd:

Number of outcomes where at least one number is odd = Total number of outcomes - Number of outcomes where both numbers are even

= 12 - 2

= 10
