Question

A coin is tossed twice. What is the probability of getting two heads ?

Answer 1

Answer:

The probability that the coin when tossed turns up heads is 1/2. This means that when the coin is tossed, the probability of tails is 1 – 1/2 = 1/2. When the coin is tossed twice, the probability of getting only tails is 1/2* 1/2 = 1/4.

Answer 2

Answer:1/4

Step-by-step explanation

:$S=(H,H) \;\;(H,T)\;\;(T,H)\;\;(T,T)\\so\;\;THESE\;are\;4\;possible\;outcomes\\Now\;\\P(2heads)=\frac{no \;of\;times\;2\;head\;comes}{total\;outcomes}=\frac{1}{4}\\\\\\\\\ Learning\;\;Together:)$
