P=0.90*0.40=0.3600

3.2.27

P= 0.10*0.10*0.10 = 0.001

3.2.23

P = (220/1100)*(219/1099) = 0.03985441

= 0.040 ( three decimals)

3.2.21

P = (1/500)*0.75 = 0.0015

3.2.20

The sample space is ( H1,H2,H3,H4,H5,H6,H7,H8,T1,T2,T3,T4,T5,T6,T7,T8)

Desired event=( H3,H4,H5,H6,H7,H8)

The required P=6/16 = 0.375
