Question

a coin is tossed 50 times and tail is obtained in 19 times. on tossing a coin at random, find the probability of getting (i) a tail (ii) a head ​

Answer 1

Answer:

i) 28 of 100 (28%)

ii) 62 of 100 (62%)

Explanation:

To get the probability of tail

19/50 × 100

19/1 × 2

28%

To get the probability of heads

(50 - 19)/50 × 100

31/50 × 100

31/1 × 2

62%

Answer 2

$\huge\sf{\mathfrak{\underline{\underline{Solution-}}}}$

$\\\sf{Total\:number \:of\: trails = 50}$

$\sf{Number \:of \:heads = 50 - 19 = 31}$

$\\\sf{(i)\bf {P (getting\: a \:tail)}}$

$\rm=\dfrac{Number\:of\:tails}{Total\:number\:of\:trails}=\bf\dfrac{19}{50}\\\\</p><p></p><p>\\\sf{(ii)\bf {P (getting\: a \:head)}}$

$\rm=\dfrac{Number \:of \:heads}{Total\:number\:of\:Trails}=\bf\dfrac{31}{50}$
