Question

A coin is tossed 150 times and the outcomes are recorded. The frequency distribution of the outcomes H (i.e, head) and T (i.e, tail) is given below :

OutcomeHT
Frequency8565

Find the value of P(H), i.e, probability of getting a head in a single trial.


  1. P(H)=0.9 (approx)
  2. P(H)=0.75 (approx)
  3. P(H)=0.15 (approx)
  4. None of these

A
P(H)=0.9 (approx)
B
P(H)=0.75 (approx)
C
P(H)=0.15 (approx)
D
None of these
Solution
Verified by Toppr


Total number of trials =150
Chances or trials which favour the outcome H= 85
P(H)= 85150 = 0.567 (approx)
