Question

two coins are tossed together find the probability of no tail ,two tail and exactly one tail

​

Answer 1

Answer:

If two coins are tossed together their outcomes are as follows :

HH,HT,TH,TT

Probability of getting two tails == 1/4

Probability of getting atleast one tail == 2/4 = 1/2

Probabilityof getting no tail is == 1/4...

...

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Probability = FOC

TOC

possible outcomes - T,T ; H,H ; T,H ; H,T (T-tail, H-heads)

Case (i) no tail

FOC : 1

TOC : 4

Probability = FOC

TOC

Therefore,

P= 1/4

Case (ii) Two Tail

FOC : 1

TOC : 4

Probability = FOC

TOC

Therefore,

P = 1/4

Case (iii) Exactly 1 tail

FOC : 2

TOC : 4

Probability = FOC

TOC

Therefore,

P = 2/4

= 1/4

FOC - Favorable OutComes.

TOC - Total OutComes.
