if one card is drawn from a standard 52 card playing deck, determine the probability of getting a ten, a king or a diamond.
IceJOKER [234]
To find the answer:

The probability of getting a ten:

=4/52

The probability of getting a king:

=4/52

The probability of getting a diamond:

=52×1/4
=13/52

However,there would be king and ten of diamond which overlapped and therefore -2/52 would be in the equation.

We can then sum up to find the equation:

=4/52+4/52+13/52-2/52
=21/52-2/52
=19/52

Therefore the answer is 19/52.

Hope it helps!

sertanlavr [38]

Answer:

2/3* 4/5 = 8/15

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached file below.

Given:

  • One-fifth (1/5)  of the playground is used for students to sit and read
  • 2/3 is used for playing soccer
  • The rest of the playground is used for playing basketball

So assume that the the playground is divided into 5 equal part

=> 1 part is used for students to sit and read or (1/5)

=>  the remaining equal part is 4  or (4/5)

Because 2/3 of the remaining part is used for playing soccer

=> the equation represents the part of the playground used for soccer is:

2/3 of 4/5

= 2/3* 4/5

= 8/15
