Question

a coin is tossed two times find the probability of getting at most one head​

Answer 1

Answer:

Answer. Probability = Favourable Outcomes / Total Outcomes. Therefore, If a coin is tossed two times then the probability of getting at one head is 3/4.

Answer 2

Answer:

$P(E) = 0.5 \: \: \: or \: \: \: \frac{1}{2}$

Step-by-step explanation:

Sample outcomes :-

(H,T),(T,H),(T,T),(H,H)

We know that,

$P(E) = \frac{number \: of \: sample \: outcomes}{total \: number \: of \: outcomes}$

Here,

Favourable outcomes = 2

Total number of outcomes = 4

$P(E) = \frac{2}{4}$

$\boxed{P(E) =0.5 \: \: \: or \: \: \: \frac{1}{2} }$
