Answer:
I think it is ether A are B
The frequency for rolling a 3 would be 5 out of 100
From the information given:
Random wins 2000 800 400 0
Probabilities 1/10^4 4/10^4 10/10^4 9985/10^4
thus the expectation will be:
E(x)=[2000+4*800+4000+9985*0]/10^4
E(x)=9200/10000
E(x)=$0.92
Perpendicular slopes have a product of -1, thus

solve for "d"
The answer would be <span>ordianl.
Hope this helps !
