Question

Two coins were tossed 200 times. The number of times 2 heads came up is 72. Then the probability of 2 heads coming up is: (a)1/25 (b)2/25 (c) 7/25 (d) 9/25​

Answer 1

Option D is correct answer.

$\text{Total number of events = 200} \\ \small \text{Total number of favourable outcomes(E) = 72}$

Now,

$\rm{P(E)} = \frac{72}{200} \\ \\ = > \frac{8 \times 9}{8 \times 25} = \green{ \frac{9}{25} }$
