Answer:
Jack must Answer minimum 28 question correctly in order to get A in Science.
Step-by-step explanation:
Given:
Percentage required = 92%
Total Number of question = 30
We need to find the number of Question answer correctly.
Solution:
number of Question answer correctly be 'x'
So we can say that;
number of Question answer correctly divided by Total Number of question multiplied by 100 should be greater than or equal to percentage required.
framing in equation form we get;

Now Dividing both side by
we get;

Hence Jack must Answer minimum 28 question correctly in order to get A in Science.

B) Probability that the selected employee has been with the firm between 5 and 10 years
= 
C) Probability that the selected employee has been with the firm more than 10 years
= 
a) P(A) = 0.2
P(C) = 0.5
P(A or B) = 0.2+0.3 = 0.5
P(A and C) = 0 (since A and C are disjoint)
