Answer:

sample space for three coins tossed is (HHT, hhh, HHT, thh, htt, tht, tth)

=>n(s)=8

Step-by-step explanation:

1. exactly two heads=(HHT, HtH,thh)

• n(P1)=3
• p1=n(p1)/ n( s)=3/8

1. At least two head(",",")

• n(p2)=4
• p2=n(p2)/n(p3)=4/8=1/2

1. at least two tail =(tTH, THT, HTT, TTT)

• n(p3)=4
• p3=n(p3)/n(p5)=4/8=1/2
