Answer:

57.6%

Step-by-step explanation:

There are four cards with a 7 and 26 cards that are black.

[tex]4+26=30[/tex]

  • There are 30 cards that are either black or have a 7 on it.

Divide the desired outcomes (30) by the number of all events (52)

[tex]\frac{Desired Outcome}{TotalEvents} = \frac{30}{52} = 0.576= 57.6%[/tex]

So there is a 57.6% that there you would be delt a card that is black or a card that have a 7.
