The answer i would pick is 2
Eccentricity = foci / half the length of the major axis
= 3.5 / 14 = 1/4
Step-by-step explanation:
Flipping a tails and rolling at least a tail are 2 independent events: they don't affect each other. So, to get the probability of both happening, we just need to multiply the probability of one by the probability of the other. he probability of rolling at least a 2 is 5/6.
