Random Experiment: An experiment in which all possible outcomes are known, and the exact output cannot be predicted in advance, is called a random experiment. Examples: Rolling an unbiased dice. Tossing a fair coin. Drawing a card from a pack of well-shuffled cards. Picking up a ball of certain colour from a bag containing balls of different colours. Details: When we throw a coin, then either a Head (H) or a Tail (T) appears. A dice is a solid cube, having 6 faces, marked 1, 2, 3, 4, 5, 6 respectively. When we throw a die, the outcome is the number that appears on its upper face. A pack of cards has 52 cards. It has 13 cards of each suit, name Spades, Clubs, Hearts and Diamonds. Cards of spades and clubs are black cards. Cards of hearts and diamonds are red cards. There are 4 honours of each unit. There are Kings, Queens and Jacks. These are all called face cards.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
