In a game a man first throws a coin. If he gets head then he puts a card from a deck of 52 cards. Find the probability to get a King of red color.

OPtion

1) 1/2
2) 1/4
3) 1/8
4) 1/26
5) 1/52
6) 13/50
7) 3/4
8) 1/10
9) incomplete data
10) none of these

Solution

Probability to get a head = 1/2
Probability to get a red King = 2/52
so required probability = (1/2)*(2/52) = 1/52

ANS:1/52
EXP:
probability for head=1/2
'' for red king=2/52
thus ans is=(1/2)*(2/52)=1/52

P(A)= probability of getting head : 1/2
P(B)= probability of getting king of red colour : 2/52

so total probability P(A and B) = P(A).P(B)=
(1/2)*(2/52)= 1/52 :)

probability of head is 1/2
and probability of red colour king is 1/26

so the total probabality is 1/52

Aparajita Chowdhury   12 years AGO

probability to get head 1/2
and probability to get a red king 2c1/52c1
so probability 1/2*2/52=1/52

selecting head=1/2
red color=26/52
king=2/26
hence, 1/2 * 26/52 * 2/26
=1/52

RIJO ROY   12 years AGO

probability for getting head while coin tosses = 1/2
probability for getting a red king = 2/52 = 1/26
so probability for getting head and red king = = 1/2*1/26 = 1/52

1/2 chances of getting head
2/52 chances of getting king red color so total chance is (1/2)*(2/52)= 1/52

Ravi kumar   12 years AGO

the probability of getting head is 1/2 and probablity of getting king of red color from deck of 52 cards is 1/26.so ans is 1/2*1/26=1/52

Ramar   12 years AGO

probability ofgetting a coin=1/2
prob of card being a king=4/52
prob of red card being a king=2/4
so tot prob=1/2*2/4*4/52

probability of getting a head is 1/2 and probabillity of getting a red king is 2/52 .. hence 1/2*2/52

amit kumar gupta   12 years AGO

first the probebility of getting head 1/2
and the probability of getting red king will be 2/52=1/26
the probability will be 1/2*1/26=1/52

anil srinivas   12 years AGO

chances for getting head=1/2
chances for getting red king = 2/52

total= 1/2*2/52= 1/52

Probability of getting head is 1/2. Probability of getting red card king is 2/52. Then the probability is calculated by multiplying 1/2 to 2/52. Then we get the answer.
