Answer:The answer are the red card(The second), A dependent event is an event that relies on another event to happen first.
Since he keep his first took red card,his probability to get another red card became lower,therefore it effects on what card he will take next.
the third one doesn't called a dependent event because it's a Dice,so the probability still the same
The fourth one doesn't count to,since he return back the marble.
3x+x-4+100 = 180
4x +96 =180
4x = 180 -96
4x = 84
x=84/4
x=21
When there are two options of the type of flower: either purple or white, the probability of purple-flowered offspring if two plants that are heterozygous for purple flowers are crossed is 3:4. Hence the answer to this problem is option C. 3:4.
