Question

A coin is tossed for 25 times and head occurred for 15 times ,then find the probability of getting tails

Answer 1

total possible outcome 25

favorable outcome= head
= total outcome - tails
= 25-15
= 10


probability (head) = 10/25
P(E) = 2 / 5

Answer 2

The probability of getting tails is 2/5

Solution:

The probability of an vent is given as:

$Probability = \frac{ \text{ number of favorable outcomes }} { \text{ total number of possible outcomes }}$

Given that,

A coin is tossed for 25 times

Head occurred for 15 times

Therefore,

Total number of possible outcomes = 25

Favorable outcomes = getting tails

Tail = 25 - 15 = 10

Thus,

Number of favorable outcomes = 10

Therefore,

$Probability = \frac{10}{25}\\\\Probability = \frac{2}{5}$

Thus, probability of getting tails is 2/5
