Plant types. A B C. D. E

Number of seedings. 100. 140. 80. 60. 40

What is the probability the farmer will randomly pick a type B plant?

1 answer

The probability of picking a type B plant is:

P(B) = Number of Type B seedlings / Total Number of Seedlings
P(B) = 140 / (100 + 140 + 80 + 60 + 40)
P(B) = 140 / 420
P(B) = 1/3
P(B) = 0.333 or 33.3% (rounded to one decimal place)
