Question

Two unbaised coins are tossed. What is the probability of getting at least one heads ?​

Answer 1

Answer:

one upon two is the probability of coin coming heads

Answer 2

Answer:

Given :

Two unbiased coins are tossed simultaneously.

To find :

At least one head

No head

Solution :

When two unbiased coins are tossed, then its total outcomes :-

Total number of outcomes = HH, TT, HT, TH

As we know that⠀⠀

$\bullet\:{\boxed{\pmb{\frak{\purple{Probability =\dfrac{ Favourable\: outcomes}{Total\:number\:of\: outcomes}}}}}}$⠀⠀

As per given condition in the question

Probability of getting at least one head

★ Number of favourable outcomes = HH, HT, TH

★ Total number of outcomes = 4

Probability of getting at least one head = 3/4

━━━━━━━━━━━━━━━━━━━━━━━━

Probability of getting no heads

★ Number of favourable outcome = TT

★ Total number of outcomes = 4

Probability of getting no heads = 1/4
