Question

In tossing a die the probability of getting an even number or a number less than 5 is​

Answer 1

GIVEN :-

• a die numbered 1 - 6

• a die is tossed once

TO FIND :-

• probability of getting any even no less than 5 after tossing dice

SOLUTION :-

$\implies \rm{total \: no \: in \: a \: dice \: =1,2,3,4,5,6}$

$\implies \rm{even \: no\: in \: dice \: = 2 ,4 ,6 }$

$\implies \rm{even \: no \:less \: than \: 5\: in \: dice \: = 2 ,4 }$

now we know that

$\implies \boxed{\rm{p(a) = \dfrac{favourable \: no \: of \: events}{total \: no \: of \: events} }}$

$\implies \rm{p(a) = \dfrac{2}{6} }$

$\implies \boxed{ \boxed{\rm{p(a) = \dfrac{1}{3} }}}$

OTHER INFORMATION

• Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.

• The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. To find the probability of a single event to occur, first, we should know the total number of possible outcomes.
