Saby 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: number on the cube number of times rolled 1 18 2 25 3 12 4 32 5 3 6 10 heads tails 56 44 using saby's simulation, what is the probability of rolling a 4 on the number cube and the coin landing heads up?

Short Answers
P(Both) = 0.1792
Givens
The total number of roles = 100
Total number of heads = 56
Number of times rolled a four =  32 [check this for me].

Set up the probabilities.
P(H) = 56/100
P(4) = 32/100
P(H)*P(4) = P(Both)

Substitute and solve
P(Both) = 56/100 * 32/100 = 1792/10000
P(Both) = 112/625 because there are many cancellations. Or you could just express it as 0.1972

Y= -2x-1 the negative in front of the 2 is because the slope is negative and the -1 is because it’s down 1 on the y axis.
