A purse contains 4 copper coins, 3 silver coins and the second purse contains 6 copper coins and 2 silver coins. If a coins is taken out of any purse
Correct Answer - A `P_(1):"4 copper coins 3 silver coins"` `P_(2):"6 copper coins 4 silver coins"` E = Event of copper coin `P(E)=P(P_(1)).P_((E//P_(1)))+P(P_(2)).P(E//P_(2))` `=(10)/(2)xx(4)/(7)+(1)/(2)xx(6)/(10)` `=(41)/(70)`

When two coins tossed simultaneously, the probability of getting at least one head is…… A) 1 B) 1/2 C) 1/4 D) 3/4
Correct option is: D)\(\frac{3}{4}\) When two coins tossed simultaneously then possible outcomes are (HH, HT, TH, TT) \(\therefore\) Total possible outcomes = 4. Favourable outcomes to event of getting at least one head are (HH,...

When three fair coins are tossed simultaneously, the probability that at least one head appears is A) 3/8
Correct option is: D)\(\frac{7}{8}\) When three coins are tossed, then possible outcomes are {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} \(\therefore\) Total possible outcomes = n(s) = 8 Outcomes which favours the event that at...

Probability of getting no head when 3 coins are tossed is A) 3/2^3 B) 2/2^3 C) 1/3^2 D) 1/2^3
Correct option is: D)\(\frac{1}{2^3}\) When 3 coins are tossed, total possible outcomes are {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} \(\therefore\) Total No of possible outcomes when 3 coins are tossed = 8 = \(2^3\) Fabourable outcome...

Two unbiased coins are tossed simultaneously. Probability of getting at most two heads is A) 1/4 B) 1/2 C) 3/4 D) 1
Correct option is: D) 1 Probability of getting at most two heads = \(\frac {No \,of \,outcomes \,which \,favours \,at \,most \,two\, heads}{Total \,No \,of \,outcomes}\) = \(\frac 44 =1\)
