Question

A coin is tossed 150 times and it is found that head comes 115 times and tail 35 times. If a coin tossed at random, what is the probability

Answer 1

115/150 is for head and for tail it would be 35/150

Answer 2

The probability the coin turns up head is 23/50 and the coin turns up tail is 7/50.

• A coin is tossed 150 times, it is found that head comes 115 times and tail 35 times.

Total experiments = 150

Number of times head turns up = 115

Number of times tail turns up = 35

• Probability that head turns up = $\frac{Number \ of \ times\ head \turns \ up}{Total \ experiments}$

P(Heads) = 115 / 150 = 23/30.

• Probability that tail turns up = $\frac{Number \ of \ times\ tails \turns \ up}{Total \ experiments}$

P(Tail) = 35 / 150 = 7/30.
