I need your help ! 1. There are 10 marbles in a bag. 6 are green, and 4 are blue. 3 marbles are taken out of the bag (and NOT put back in). What is the probability that all 3 are green?

2. There is a bag of red and blue marbles and a deck of cards. A marble is picked and a card is drawn. You win the wager if either a blue marble is drawn or a spade is drawn. You have a 70 percent chance of winning this deal. How many blue marbles are in the bag? How many total marbles are in the bag? There is more than one correct answer.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
