A shopkeeper sells three types of flower seeds A1,A2,A3A_1, A_2, A_3. They are sold as a mixture where the proportions are 4 : 4 : 2 respectively. The germination rates of the three types of seeds are 45%, 60% and 35% respectively. Calculate the probability in the following cases.

The probability that seed is of type A1A_1 given that seed doesn't germinate.

Solution

✅ Correct Option: 4

P(not G)=1−0.49=0.51P(\text{not } G) = 1 - 0.49 = 0.51.

P(A1∩not G)=P(A1)⋅P(not G∣A1)=0.4×0.55=0.22P(A_1 \cap \text{not } G) = P(A_1) \cdot P(\text{not } G | A_1) = 0.4 \times 0.55 = 0.22.

P(A1∣not G)=0.220.51=2251P(A_1 | \text{not } G) = \frac{0.22}{0.51} = \frac{22}{51}.
