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!

Neither one will ever hit the axis I think? if its x=3.5 then its horizontal but its above the x axis. Same with the second one. its vertical and will never hit the y axis. Not sure how to write that into those boxes but I think there isn't an intercept.

The 982 part seems wrong. Are you sure it isn't 981?

around 436 if I use 981 instead. 982 would give a decimal and that would be kinda weird for a part human.

Step-by-step explanation:

You can divide the 205 by 5 to simplify the ratio down. 205/5 = 41. Then you can multiply by 4 to find then number of boys.

981

So you can add the 5 and 4 together to 9 and then divide 981 by 9 to get 109. Then you can multiply by 4 to get 436.

Hope this helps!
