Yes
Step-by-step explanation:
Since P(A)=0.7 and P(A and B)=0.28, then P(B) must be 0.4 because 0.7*0.4=0.28.
Since P(A and B) is a combined probability, P(A) and P(B) are independent.
Tim : Sam : Total
1 : 4 : 1+4
1 : 4 : 5

x = 8
x = 8
4x = 8x4 = 32
Tim : Sam
1 : 4
£8 : £32
So Tim = £8 and Sam = £32
