Question

2 coind are tossed 40 times plz tell the probabilty of head tail no tail no head ​

Answer 1

Coin tossed =40 times

showed tail =14 times

Probability (getting head) =  40-14/40

=26/40

      =1.538461

p(h) = 1/2 (there are two possible outcomes(head and tail, and count is 2), and out of that the expected outcome is just head which counts as 1)

p(h) = 1/2 (there are two possible outcomes(head and tail, and count is 2), and out of that the expected outcome is just head which counts as 1)p(t) = 1/2 ( same as previous one)

p(h) = 1/2 (there are two possible outcomes(head and tail, and count is 2), and out of that the expected outcome is just head which counts as 1)p(t) = 1/2 ( same as previous one)So probability of getting exactly a single head while tossing single coin is 1/2.

p(h) = 1/2 (there are two possible outcomes(head and tail, and count is 2), and out of that the expected outcome is just head which counts as 1)p(t) = 1/2 ( same as previous one)So probability of getting exactly a single head while tossing single coin is 1/2.Lets figure out all the different outcomes while tossing three different coins.
