Answer 1

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
