Answer:

$\bold{Question:-}$

coin is tossed 400. We obtain a tail 260 times on tossing the coin at random.Find the probability of getting a head

$\bold{Answer:-}$

$\sf\fbox\pink{Total outcomes = 500}$

$\sf\fbox\pink{Head = 500 - 260}$

$\sf\fbox\pink{= 240}$

(i) p ( getting a head ) $=\frac{260}{500} \\ = \frac{13}{25}$

( ii ) p ( getting a tail ) $=\frac{240}{500} \\ =\frac{12}{25}$

Answer 2

Answer:

Given,

Total number of events = 500

No. of times heads occur = 285

Probability of getting head when coin is tossed at random = 285/500 = 57/100

No. of times tails occur = 215

Probability of getting tails when coin is tossed at random = 215/500 = 43/100
