Given:
A spinner marked A, B, C is spun then a 6-sided die is rolled.
To find:
The probability of getting a B and then a 6.
Solution:
We know that,
Total possible values for a spinner are 3. So, the probability of getting B, we get
Total possible values for a die are 6. So, the probability of getting 6, we get
Now, the probability of getting a B and then a 6 is
The required probability is .
Therefore, the correct option is D.
Answer: ? = 72
Step-by-step explanation:
We will set up a proportion to solve.
Now, we will cross-multiply.
? * 35 = 56 * 45
