Question

#l The letters of the word SUMMER are printed on 6 cards.
(a) A card is chosen at random. Write down the probability that it has the letter R printed on it.
(b) Find the probability that the card chosen at random does not have the letter M printed on it.
(c) Find the probability that the letter printed on the card chosen at random has no lines of symmetry.
(d) Chris chooses a card at random, replaces it, then chooses a card again. Calculate the probability that only one of the cards she chooses has the letter M printed on it.
(e) Graham chooses a card at random and does not replace it. He continues until he chooses a card with the letter M printed on it. Find the probability that this happens when he chooses the 3rd card.

Answer 1

Answer:

a)1/6

b)2/3

c)1/6

d)1/9

e)1/15

Step-by-step explanation:

i)R is one out of the 6 letters

Hence probability is 1/6

ii)m is 2 out of the 6

Probability of m missing =6/6-2/6

=4/6

=2/3

iii) R has no lines of symmetry

=1/6

iv)=2/6*2/6=4/36

=1/9

v)2/6*2/5*2/4

=1/15
