A money envelope contains five $10 bills 10 $20 bills and 15 $50 bills Sandra randomly selects two bills without returning the first bill. What is the probability of getting a $10 bill then a $50 bill write your answer in the simplest form of fraction
First, calculate the total number of bills in the envelope:
5 + 10 + 15 = 30 bills
Next, calculate the probability of selecting a $10 bill first:
5 / 30 = 1 / 6
After selecting the $10 bill, there are now only 29 bills left in the envelope.
Now, calculate the probability of selecting a $50 bill second:
15 / 29
Therefore, the probability of getting a $10 bill followed by a $50 bill is:
(1/6) * (15/29) = 5 / 58
So, the probability of getting a $10 bill then a $50 bill is 5/58.
