Provided that:

  • Yellow marbles in bag = 5
  • Blue marble in bag = 10

To find:

  • The probability of choosing yellow marble from the bag.

Solution:

  • The probability of choosing yellow marble from the bag must be 1/3

Using concept:

  • Formula to calculate probability

Using formula:

{\sf{\dfrac{Number \: of \: outcomes \: that \: make \: an \: event}{Total \: number \: of \: outcomes \: of \: the \: experiment}}}

Required solution:

:\implies \sf \dfrac{Number \: of \: outcomes \: that \: make \: an \: event}{Total \: number \: of \: outcomes \: of \: the \: experiment} \\ \\ :\implies \sf \dfrac{5}{10+5} \\ \\ :\implies \sf \dfrac{5}{15} \\ \\ :\implies \sf \dfrac{1}{3} \\ \\ :\implies \sf Probability \: = {\boxed{\dfrac{1}{3}}}

→ A “random experiment” is one whose outcomes cannot be predicted exactly in advance.

→ There are certain experiments whose outcomes have an equal chance of occuring.

→ Outcomes of an experiment are “equally likely” if each has the same chance of occuring.

→ Probability of an event =

{\underline{\boxed{\sf{\dfrac{Number \: of \: outcomes \: that \: make \: an \: event}{Total \: number \: of \: outcomes \: of \: the \: experiment}}}}}

→ Chances and probability are related to real life.

→ One or more outcomes of an experiment make an “event”.

→ The sum of all the probability in an event must be always 1

→ Probability of an event must be lie between 0 and 1 always like 0.55 etc

→ P(E) + P(Ē) = 1

Where, P(E) is happening probability of an event and P(Ē) is probability of that event which isn't happening
