Answer: (a) 0.28, (b) 0.14, (c) 0.57 and (d) 0.
Step-by-step explanation:
Probability = [tex]\frac{FO}{TO}[/tex]
where,
FO represents favorable outcomes and TO represents total outcomes
(a) In this part, FO = 2 and TO = 7
So, the probability = [tex]\frac{2}{7}[/tex]
= 0.28
(b) In this part, FO = 1 and TO = 7
So, the probability = [tex]\frac{1}{7}[/tex]
= 0.14
(c) In this part, FO = 4 and TO = 7
So, the probability = [tex]\frac{4}{7}[/tex]
= 0.57
(d) In this part, FO = 0 and TO = 7
So, the probability = [tex]\frac{0}{7}[/tex]
= 0
