एक मानक निष्पक्ष छह-तरफा पासे (die) को एक बार फेंकने पर संभावित परिणामों (फलक के मान को दर्शाने वाले यादृच्छिक चर के मानों) की कुल संख्या कितनी होती है?

A box contains 'x + 4' red, 'x – 1' green and 'x – 5' blue balls. If two balls are drawn from the bag one after another without replacement, then the probability of getting one red and one green ball is equal to the probability of getting a sum equal to or more than 8 when two fair dice are rolled. Find the probability of drawing a red ball when one ball is drawn at random from the bag.

Four persons are chosen at random from a group containing 3 men, 2 women, and 4 children. The probability that exactly two of them are children is:
