HELP I also need the answer to this

ser-zykov [4K]

Hey!

To divide fractions, you have to keep, change, flip.

Keep 3 1/2(7/2)

Change ÷ to ×

Flip 2 1/4(9/4) = 4/9

Now multiply the improper fractions

$\frac{7}{2} \times \frac{4}{9} = \frac{28}{18} = 1 \frac{10}{18} = 1 \frac{5}{9}$

The 1st choice matches the answer. The answer is the 1st choice.

Good luck and hope this helps! :)

The correct answer for this question is this one: "C. P(C | A) = 0.75, P(C)=0.75 the events are not independent."

The statement that can be determined about events A and C from the table is that P(C | A) = 0.75, P(C)=0.75 the events are not independent. Hope this helps answer your question.
