Probability ( a flowering plant or fruit plant) is
and Probability (neem plant or peepal plant) is
.
Step-by-step explanation:
Given,
Number of neem plant = 125
Number of peepal plant = 165
Number of creppers plant = 50
Number of fruit plant = 150
Number of flowering plant = 110
To find the probability ( a flowering plant or fruit plant)
and probability ( neem or peepal)
Formula
P( A or B) = P(A) + P(B)
Probability ( a flowering plant or fruit plant) = 
=
= 
And,
Probability (neem plant or peepal plant) = 
=
= 
Answer:
b. Kathy
Step-by-step explanation:
We compare each of their score by how far away from the mean when in term of the standard deviation. Using the following formula

For John he is (85 - 75)/5 = 2.
For Kathy she is (80 - 50)/10 = 3.
Since Kathy is 3 standard deviation better than her class' average, while John is only 2's. We conclude that Kathy did better.
