Question

1. toss two coins simultaneously ten times and record your observation in the table. (a) number of times no head comes up.(b) number of times one head comes up. (c) number of times two head comes up.​

Answer 1

Total no. of outcomes = 4{(H,H)(T,T)(H,T)(T,H)}

Let 'P' be the probability of an event occuring

$\huge{\boxed{Formula:-}}}$

${\boxed{\red{{Probability} =\frac{No. \: of \: possible \: outcomes}{Total \: no. \: of \: outcomes}}}}$

a) P(no head) = $\frac{1}{4}$

b) P(one head) = $\frac{2}{4} =\frac{1}{2}$

c) P(two head) = $\frac{1}{4}$
