Question

6) If a coin is thrown three times what is the probability of getting heads all three times ?​

Answer 1

Step-by-step explanation:

If the coin is thrown three times=>

S = [ HHH, HTH, THH, TTH, HHT, HTT, THT, TTT ]

n(S) = 8

Event A: getting heads all three times

A= [ HHH ]

n(A) = 1

P(A) = n(A) / n(S) = 1/8

Hope it helps uh!!!!!

Answer 2

$\huge\bf\underline{Question:}$

If a coin is thrown three times what is the probability of getting heads all three time?

$\huge\bf\underline{Solution:}$

Following are the outcomes possible when a coin is tossed three times,

S = {HHH, TTT, HTT, HHT, HTH, TTH, THT, THH}

n(s) = 8

A = getting heads all the three times

A = {HHH}

n(A) = 1

P(A) = $\frac{n(A)}{n(s)} = \frac{1}{8}$

Therefore, the probability of getting heads all the three times is 1/8.

Probability:

Its the measure of chance of an event to happen.

E=Event

P(E)=Probability of Event E

$P(E)=0\leqslant P(E) \leqslant 1$
