Step-by-step explanation:
the area of a triangle is
baseline × height / 2
we have here 2 triangles : the larger, outer shaded one, and the smaller, inner white one.
to get the area of the shaded part, we need to calculate the area of the large triangle and subtract the area of the smaller triangle.
large area :
12 × 15 / 2 = 6 × 15 = 90 ft²
small area :
8 × 10 / 2 = 4 × 10 = 40 ft²
the shaded area is
90 - 40 = 50 ft²
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) = 
=
=
