Question

Three coins are tossed simultaneously 1000 times
and we get the following observations: Three heads
= 216
Exactly 2 heads = 384, Exactly 1 head = 270,
No heads = 130
Then probability of non-occurrence of exactly 2
heads is
(a) 0.616
(b) 0.384
(c) 0.4
(d) 61.6​

Answer 1

then use then use 100 in 1000 x 216 is equal to 1216 this is your answer

• answer question answer is 10:00

Answer 2

Answer:

a)0.616

favourable outcome=1000-384

=616

possible outcome=1000

probability of non occurrence of exactly 2 heads=616/1000.

=0.616
