Question

22. coins are tossed 600 times and we get
w heads138 times, one head : 192 times; no head : 270times.
When two coins are tossed at random, what is the probability of getting :(i) 2 heads (ii) 1 head (iii)
a head (iv) at least 1 head (v) at most 1 head

Answer 1

Answer:

at least 1 head

I hope you

Answer 2

Answer:

Step-by-step explanation:

i.p(getting 2 heads)=no.of trials which get 2 heads /total no. of trials

=138/600

=23/100 ans.

similarly,

ii.p(getting 1 head)=192/600

=8/25 ans.

iii.p(getting a head)=(138+192)/600

=330/600

=11/20 ans.

iv. it has same answer as that of qñ no.iii.

v.it has same answer as that of qñ no. ii.
