Gnoma [55]

Answer:

a) 0.06

b) 0.3

c) 0.44

Step-by-step explanation:

We are given the following in the question:

A and B are two independent events.

P(A) = 0.3

P(B) = 0.2

a) P(A intersect B)

$P(A\cap B) = P(A)\times P(B) = 0.3\times 0.2 = 0.06$

b) P(A|B)

$P(A|B) = \dfrac{P(A\cap B)}{P(B)} = \dfrac{0.06}{0.2} = 0.3$

c) P(A union B)

$P(A\cup B) = P(A) + P(B) - P(A\cap B)\\P(A\cup B) = 0.3 + 0.2 - 0.06 = 0.44$

A bag contains 12 pennies, 9 nickels, 11 dimes and 3 quarters. A coin is selected at random from the bag. Find the probability.

steposvetlana [31]

Probablity=desiredoutcomes/totalpossibleoutcomes

see which ones fit
dimes and quarters are over 9 cents
there are 11+3 or 14 of them

total outcomes=12+9+11+3=35

probablity=14/35=2/5

probablity is 2/5
