Answer:
it is so simple yrr
Step-by-step explanation:
it has a formula for probability
the no. of trials in which the event happened/ total no. of trials.
We know that in a coin their are 2 probabilities
of getting a head or a tail when we toss it and in two coins we get 4 probabilities head, tail, head, tail.
Done??? yaha tak smjh gayi? Ab aage Dekho
here we take (i) 2 head
total trials or probabilities we have are 4 ( because of two coins)
and the event is 2 (BECAUSE 2 HEADS GIVEN IN THE QUESTION)
now apply the formula the no. of trials in which the event happened/ total no. of trials.
okay???
so 2/4 = 2 is the answer for (i)
similarly for one head means no. of trial in which event happened is 1
so similarly (ii) 1/4 is the answer
(iii) 1/4
(iv)2/4= 2
