Answer: \dfrac{7}{10}

Step-by-step explanation:

Given : Total sports cards = 50

Number of football cards = 20

Number of basketball card = 15

Probability of getting a foot ball card =\dfrac{\text{No. of football card}}{\text{Total carrds}}

=\dfrac{20}{50}

Probability of getting a basketball card =\dfrac{\text{No. of basketball card}}{\text{Total carrds}}

=\dfrac{15}{50}

Since each card is different from another , so the events of drawing any card are independent.

In this case P(foot ball card or basket ball card)= P(foot ball card ) +P(basketball card)

=\dfrac{20}{50}+\dfrac{15}{50}=\dfrac{35}{50}=\dfrac{7}{10}

Thus , the probability that the card is a football card or basketball card is \dfrac{7}{10} .
