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.
Evaluate 1.80/Y for y= 0.009
We replace 0.009 for y
So fraction becomes
Now , to simplify the fraction we try to remove the decimal from denominator
0.009 have three digits after the decimal point, so we multiply by 1000 to remove the decimal point. Multiply top and bottom by 1000 to make equivalent fraction.
= 200
Answer is 200
