Question

two coin are tossed simultaneously 500 times and we get two head = 105 times one head =275 no head = 120 times​

Answer 1

Given :

• Two coins are tossed simultaneously with Two head =105 times, one head =275 times and no head =120 times.

To Find :

• Probability of getting two heads ,one head and no head.

Solution :

1.Two heads = 105 times

${P(Two\:heads)=\dfrac{No.\:of\:fav.\:Outcomes}{Total\:no\:of\:Outcomes}}$

$\longmapsto\tt{\cancel\dfrac{105}{500}}$

$\longmapsto\tt\bold{0.2}1$

So , The probability of getting Two Heads is 0.21..

2.One head =275 times

${P(One\:head)=\dfrac{No.\:of\:fav.\:Outcomes}{Total\:no\:of\:Outcomes}}$

$\longmapsto\tt{\cancel\dfrac{275}{500}}$

$\longmapsto\tt\bold{0.55}$

So , The probability of getting One Head is 0.55..

3.No head =120 times

${P(No\:head)=\dfrac{No.\:of\:fav.\:Outcomes}{Total\:no\:of\:Outcomes}}$

$\longmapsto\tt{\cancel\dfrac{120}{500}}$

$\longmapsto\tt\bold{0.24}$

So , The probability of getting no head is 0.24..
