The number of books issued from a public library In a week are 1028, 1129, 1538, 1605, 1236,1575 ,1611.Find the probability that the number of books issued on a day is less than 1500 and more than 1500
Answers
Answer:
12/49
Step-by-step explanation:
Probability = Number of outcomes/Total number of outcomes
We have 7 days and hence we have 7 possible outcomes.
We want :
1) The probability that the number of books issued on a day is less than 1500.
2) The number of books issued in a day is more than 1500.
We will begin with the first question.
1) Probability that books issued is less than 1500
The possible outcomes are :
1028,1129,1236
There are 3 outcomes out of a total of 7 outcomes.
From the formula above the probability is given by :
3/7
2) Probability that the books are more than 1500.
The possible outcomes are :
1538,1605,1576,1611
There are four outcomes.
The probability is therefore given by :
4/7
Now we want :
P(less than 1500) and P(more than 1500)
This is elaborated as :
P(less than 1500) ×P(more than 1500)
= 3/7 × 4/7 = 12/49
