Open in App

Solution

Total number of outcomes = 50
Multiples of 3 and 4 which are less than or equal to 50 are:
12,24,36,48
Favourable number of outcomes = 4
Probability of the number being a multiple of 3 and 4
$= \frac{N u m b e r o f f a v o u r a b l e o u t c o m e s}{T o t a l n u m b e r o f o u t c o m e s} = \frac{4}{50} = \frac{2}{25}$
