Will mark brainliest if possiblecathy used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. the results are shown in the tables below: color of marble number of times rolled blue 12 green 18 yellow 20 heads tails 30 20 using cathy's simulation, what is the probability of pulling a blue marble and the coin landing tails up? 240/2500 220/2500 12/50 32/50

240/2500

Step-by-step explanation:

A:event of drawing a blue marble from bag

P(A)=number of blue marble/total marbles

      = 12/50

B:event of getting tails on tossing a coin

P(B)=total tails/total tosses

      = 20/50

A∩B:event of getting a blue marble and tails on coin

As we know the two events are independent

Hence, P(A∩B)=P(A)×P(B)

                        =

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
