Question

2.coin are tossed of simulated i describe the sample space find the probability of getting 1) two head 2)at least one head 3 )at most one hand number 4) hand number 5 )no head number 6 )at most two head ​

Answer 1

Step-by-step explanation:

When two coins are tossed once, the sample space is given by <br>

and, therefore, n(S) = 4. <br> (i) Let

= event of getting 2 heads. Then, <br>

and, therefore,

. <br>

P (getting 2 heads)

<br> (ii) Let

= event of getting at least 1 head. Then, <br>

and, therefore,

. <br>

P (getting at least 1 head)

<br> (iii) Let

= event of getting no head. Then, <br>

and, therefore,

. <br>

P (getting no head)

<br> (iv) Let

= event of getting 1 head or 1 tail. Then, <br>

and, therefore,

. <br>

P (getting 1 head and 1 tail)
