Two events, A and B, are independent. If P(A) = 0.3 and P(B) = 0.2, what is P(A and B)?

Flura [38]

Answer:0.06

Step-by-step explanation:

As the two events are independent

Therefore

$P(AandB) =P(A)\times P(B)$

As it is given that $P(A) = 0.3$ and $P(B) = 0.20$

Putting these value we get

$P(AandB) =0.3\times0.2 = 0.06$

$P(AandB)= 0.06$ is the required answer

brilliants [131]

Tina said that 6:8 is equal to 36:64.
It's wrong. It should be 48:64. Because just like a fraction, whatever you multiply in the bottom, you do to the top.
