Statistics - Probabilities
26. Six dice are thrown simultaneously. The probability that all will show different faces is
- Option : B
- Explanation : Number of ways different numbers can occur
on six dice = 6!Total number of ways of occurrence = 65
Required probability,
- Option : A
- Explanation : Probability of drawing a white ball from Box B will depend on whether
transferred ball is black or white.
If a black ball is transferred then its probability is 4/6
There are now 5 white and 8 black balls in the
box B. Then probability of drawing white ball
from the Box B = 5/13
Hence probability of drawing a white ball from
urn B, if the transferred ball is black
Similarly, probability of drawing a white ball
from urn E, if transferred ball is white
