Sample space: {HHH, HTH,THH,TTH, HHT, HTT,THT,TTT}
Total number of possible outcomes=8
Probability of getting at least two heads is:
P(A)=P(getting two heads)+P(getting 3 heads)
= 3/8 + 1/8
= 4/8 = 1/2 = 0.5

P(X U Y) = P(X) + P(Y) - P(X ∩ Y).
Since X and Y are independent events therefore
P(X ∩ Y) = P(X) x P(Y).
0.6 = P(X) + 0.3 - P(X) x 0.3
0.6 = 0.7 P(X) + 0.3
0.3 = 0.7 P(X)
P(X) = 0.3/0.7
=3/7

Let A be the event boy speaks truth
P(A)=2/3
Let B be the Event dice shows 3
P(B) = 1/6
using Bayes therorem
P(B|A) = (P(B).P(A|B))/( P(B) . P(A|B) + P(~B). P(A|~B) )
= (2/18)/(2/18 + 5/18) =2/7

First find the probability that NO heads turn up i.e., five tails.
That would be (1/2)5 = 1/32.
For at least one heads to occur is the complement of all tails. It`s probability is 1 - 1/32 = 31/32

There are total 13 cards of club, so probability that one card is spade is 13/52
According to the questions cards are drawn without replacement. So only 51 cards are left.
Again there are 26 red cards and only two among them are kings
So probability of red king is 2/51
Probability that one card is a club and other card is king of red colour is 13/52 * 2/51 = 1/102
