Probability of all 3 calculators being good = 0.971.
<u>Step-by-step explanation:</u>
We have , A sample of 3 different calculators is randomly selected from a group containing 17 that are bad and 36 that are good. In order to calculate that all 3 randomly selected calculators are good , let's calculate probability of all 3 being bad and subtracting value by 1. i.e. Probability of all 3 being good = 1 - Probability of all 3 being bad
⇒ Probability of all 3 being bad =
×
×
= 4193/148877
∴Probability of all 3 being good = 1 - Probability of all 3 being bad
⇒ 
⇒
∴Probability of all 3 calculators being good = 0.971.
Answer:
21 questions
Step-by-step explanation:
First find the unit rate by dividing question number by hours
35/5=7
So he makes 7 questions per hour
Multiply 7 by 3
7*3=21
So, he makes 21 questions in 3 hours
Hope this helps! :)
