Question

Three coins are tossed simultaneously 600 times with the following

frequencies of different outcomes. Find

OUTCOMES FREQUNCY

3 heads 150

2 heads 200

1 head

100

No head 150

a) The probability of getting 3 heads​

Answer 1

Answer:

Total number of outcomes = 100

Answer 1) :2 heads coming up Probability = 36/100

= 9/25

Answer 2) :3 heads coming up Probability = 12/100

= 3/25

Answer 3): At least 1 head coming up Probability = (36/100 + 38/100 + 12/100)

86/100 =

= 43/50

Answer 4): Getting more heads than tails Number of times 2 heads (2 heads and 1 tail)

appears = 36

Number of times 3 heads (3 heads and O

tail) appears = 12

Number of favorable outcomes = 36 + 12 =

48

Probability (Getting more heads than tails) = Number of favorable outcomes/Total

number of possible outcomes

= 48/100

= 12/25

Answer 5): Getting more tails than heads Number of times 2 tails (2 tails and 1 head)

appears = 38

Number of times 3 tails (3 tails and O head)

appears = 14

Number of favorable outcomes = 38 + 14 = =

52

Probability (Getting more tails than heads) =

52/100

= 13/25
