Question

A coin tossed 850 times with the following frequencies. Head =355. Compute the probability for (1) head (2) tail.

Answer 1

no.of tosses=850
head = 355
p(h)= 355/850
=0.4176

tail = 850-355
= 495
p(t)=495/850
=0.5823

Answer 2

Total no of outcomes = 850.
Number of favorable outcomes for head = 355
Remaining favorable outcomes for tail = 850 - 355 = 495

Probability of an Event =  Number of Favorable Outcomes / Total Number of Possible Outcomes

Probability of getting head = 355/850 = 71/170 = 0.4176
Probability of getting tail = 495/850 = 99/170 = 0.5823
