Vedclass · Answer

(A) The probabilities of ships $A, B$ and $C$ arriving safely are calculated from the given odds in favor.For ship $A$,the probability $P(A) = \frac{2}{2 + 5} = \frac{2}{7}$.For ship $B$,the probability $P(B) = \frac{3}{3 + 7} = \frac{3}{10}$.For ship $C$,the probability $P(C) = \frac{6}{6 + 11} = \frac{6}{17}$.Since the events are independent,the probability of all ships arriving safely is $P(A \cap B \cap C) = P(A) 	imes P(B) 	imes P(C)$.$P(A \cap B \cap C) = \frac{2}{7} 	imes \frac{3}{10} 	imes \frac{6}{17} = \frac{36}{1190} = \frac{18}{595}$.

Three ships $A, B$ and $C$ sail from England to India. If the ratio of their arriving safely are $2 : 5, 3 : 7$ and $6 : 11$ respectively,then the probability of all the ships arriving safely is:

There are three events $A, B, C$,one of which must and only one can happen. The odds are $8:3$ against $A$,$5:2$ against $B$,and the odds against $C$ are $43:17k$. Then the value of $k$ is:

$A$ card is drawn from a pack of $52$ cards. Find the probability that the card will be a queen or a heart.

The probability of an event happening is the square of the probability of a second event,but the odds against the first are the cube of the odds against the second. The probabilities of the events are:

Statement $- I :$ If the probabilities of solving a problem by $A$ and $B$ are $1/3$ and $1/4$ respectively,then the probability that the problem is solved is $7/12$.
Statement $- II :$ The events described above are independent events.

If $P(A) = 0.4$,$P(B) = x$,$P(A \cup B) = 0.7$ and the events $A$ and $B$ are independent,then $x =$
