Thank you !

Answer 2

Answer:

Sample space = {HH, HT, TT, TH}

No. of Outcomes = 4

(a) P (2 heads) = 1/4

= 0.25

(b) P (one head) = 1/4

= 0.25

(c) P (no head) = 1/4

= 0.25

[Because no head means only tail]

(d) P (atleast one head) = 3/4

= 0.75

[Atleast one head means head can occur more than 1 time]

(e) P (at most one head) = 3/4

= 0.75

[At most means that the maximum number of times head can occur]
