Question

A coin is tossed 150 times, and heads appear 83 times. If one toss is chosen at random, find the probilities of getting (i) heads and (ii) tails.

Answer 1

Answer:

Total number of trials =150

Chances or trials which favour the outcome H= 85

P(H)= 85

150

= 0.567 (approx)

Answer 2

Step-by-step explanation:

SOLUTION

Total number of experiments = 150

Number of appearances of heads = 83

=> number of appearances of tails = 150 - 83 = 67

(1) The probability of getting heads is

P (getting heads) = number of times heads appear / total number of tosses = 83/150

(2) The probability of getting tails is

P(getting tails) = 67/150.
