If A and B are independent events, then the probability of A happening AND the probability of B happening is P(A) × P(B).
P(A and B) = P(A) × P(B)
If a dice is thrown twice, find the probability of getting two 5’s.
Two sets of cards with a letter on each card as follows are placed into separate bags.
Sara randomly picked one card from each bag. Find the probability that:
a) She picked the letters ‘J’ and ‘R’.
b) Both letters are ‘L’.
c) Both letters are vowels.
a) Probability that she picked J and R =
b) Probability that both letters are L =
c) Probability that both letters are vowels =
Two fair dice, one coloured white and one coloured red, are thrown. Find the probability that:
a) the score on the red die is 2 and white die is 5.
b) the score on the white die is 1 and red die is even.
a) Probability the red die shows 2 and white die 5 =b) Probability the white die shows 1 and red die shows an even number =
