Question

two coins are tossed simultaneously the probability of getting almost one head is​

Answer 1

Answer:

If we consider

the Event of getting a Head as H

Ad , the Event of getting a Tail as T

Now , when we toss a coin , the sample space woule be S = { HH , HT , TH , TT }

Therefore , n ( S ) = 4

then , there would be two favourable cases :

1. We get 1 Head { HT , TH }

2. We get 2 Heads . { HH }

So , if we consider these favourable cases as the Event A , then n ( A ) = 3

Therefore , P( A ) = n( A ) / n ( S )

= 3 / 4 [ Ans. ]

Answer 2

Answer:

When two coins are tossed simultaneously then the possible outcomes obtained are {HH, HT, TH, and TT}. Here H denotes head and T denotes tail. Therefore, a total of 4 outcomes obtained on tossing two coins simultaneously. Number of favourable outcome(s) for no head is {TT} Number of favourable outcome(s) for one head is {HT, TH} Therefore, the event of getting at most one head has 3 favourable outcomes. These are TT, HT and TH. Therefore, the probability of getting at most one head = 3/4.Read more on Sarthaks.com - https://www.sarthaks.com/697228/two-coins-are-tossed-simultaneously-what-is-the-probability-of-getting-at-most-one-head
