Question

kindly help me with this exercise thank you!

answer exercise 2.3 only

Exercise 2.2 (Probability of Joint Event) Test results of scratch resistance and shock
resistance for 100 disks of polycarbonate plastic are as follows:
Shock Resistance
High (B)
80
6
Low (B')
Scratch
Resistance
High (A)
Low (A')
5
Let A and A' denote the event that a disk has high scratch resistance and the
event that a disk has low scratch resistance, respectively. Let B and B' denote
the event that a disk has high shock resistance and the event that a disk has low
shock resistance, respectively.
1. When a disk is selected at random, find the probability that both the scratch
and shock resistances of the disk are high.
2. When a disk is selected at random, find the probability that the scratch or
shock resistance of the disk 1s high.
3. Consider the event that a disk has high scratch resistance and the event that a
đisk has high shock resistance. Are these two events mutually exclusive?
Exercise 2.3 (Conditional Probability) In Exercise 2.2, find the probability that a disk
has high scratch resistance (4) when it has high shock resistance (B).
