(a+b):2=2010=>a+b=4020
a-b=808
adunam relatiile:
a+b+a-b=4020+808
2a=4828
a=2414=>b=2414-808=1606

S=Max2=2010x2=4020

a+b=4020

a-b=808, a=808+b,

808+2b=4020

2b=3212

b=1606

a=2414

Dan used a probability simulator to roll a 6-sided number cube and flip a coin 100 times.

The results are shown in the tables below:

Numbers on the Cube: 1, 2, 3, 4, 5, 6
Number of Times Rolled: 19, 26, 13, 23, 8, 11

Heads: 48
Tails: 52

Using Dan's simulation, what is the probability of rolling a 4 on the number cube and the coin landing heads up?

Answers:
