Probability using a table what have i done wrong?

A and B are correct.  

C.

P(both choose D og) = 0.4 × 0.4 = 0.16

For independent events, we have to multiply the probabilities for the probability of the conjunction, "AND"

0.16

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
