1/4 should be the answer :)
Divide the total number correct, by the total number of questions on the test. 42/60=70%
To answer this, you would divide 14 pears / 4 people. The answer would be 3 1/2 pears per person.
Answer:
Option 4: 0.554
Step-by-step explanation:
As we can see that the intervals and their frequencies are given.
We have to calculate the probability of students' score falling between 70 and 89. It will use the frequency of both intervals 70-79 and 80-89.
So, combined scores of both intervals are:
172+105 = 277
Now to find the probability
= 277/500
=0.554
So option no 4 is the correct answer ..
