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) =
= =
Step 1 : subtract 1 from both sides
Step 2 : Divide both sides by 3
Step 3 : Find the square root of 9
x= (-3,3)
remember negative × negative = positive
