The probability P(less than 7) is 3/4.

What is probability?

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.

For the given situation,

The cards are numbered as s = {4,5,6,7}

⇒$n(s)=4$

The event is probability of picking the cards less than 7

Cards less than $7$ ,  $e=4,5,6$

⇒$n(e)=3$

Probability of picking the card is given by $p(e)=\frac{n(e)}{n(s)}$

On substituting the values,

⇒$p(less than 7)=\frac{3}{4}$

Thus the probability P(less than 7)  is 3/4.
