Question

a coin in tossed 20 times and tail comes 15 times? what us probability of occurence of head
show step by step ​

Answer 1

Answer:

0.25

Step-by-step explanation:

Probability of head = (no. of head)/ (total number of times coin is thrown)

= (20-15)/20

=5/20

=0.25

Hope this helps!

Answer 2

Answer:

Coin tossed = 20 times

Tails = 15 times

If tails come 15 times, then heads come = 20 - 15 = 5 times

Formula:-

P(E) = $\frac{No. of outcomes}{Total outcomes}$

No. of outcomes of heads = 5

Total outcomes = 20

⇒P(Heads) = $\frac{5}{20}$

⇒P(Heads) = 0.25
