Question

Three coins are tossed simultaneously 400 times and following frequencies of
outcomes were recorded
Outcomes
Frequency
3 heads
103
2 heads
124
1 head
No head
(1) Find the probability of getting no head
(ii) Find the probability of getting 1 head
in Find the probability of getting exactly 2 heads

​

Answer 1

Answer:

one head is get because tali is not come

because coin is always get tali

Answer 2

probability ( no head ) = $\frac{73}{400}$

probability  ( 1 head ) = $\frac{100}{400}$

probability (exactly 2 heads ) = $\frac{124}{400}$

Step-by-step explanation:

assuming the frequency of 1 head and no head is 100 and 73

given : Three coins are tossed simultaneously 400 times

total number of outcome = 400

outcomes   frequency

3 heads        103

2 heads        124

1 head           100

no head          73

then

probability = $\frac{number of outcome}{total outcome}$

probability ( no head ) = $\frac{73}{400}$

probability  ( 1 head ) = $\frac{100}{400}$

probability (exactly 2 heads ) = $\frac{124}{400}$
