An urn contains 5 white and 10 black balls. A fair die is rolled and that number of balls is randomly chosen from the urn.
What is the probability that all of the balls selected are white?
What is the conditional probability that the die landed on 3 if all the balls selected are white?

You can still ask an expert for help

1.Events:

A- ll of the choose balls are white

Probabilities:

Since the die is fair:

If the die rolls i we choose a combination of i balls, among black and five white balls, therefore

Calculate:

The spring of a spring gun has force constant k =400 N/m and negligible mass. The spring is compressed 6.00 cm and a ball with mass 0.0300 kg is placed in the horizontal barrel against the compressed spring.The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.00 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is held so the barrel is horizontal. Calculate the speed with which the ballleaves the barrel if you can ignore friction. Calculate the speed of the ball as it leavesthe barrel if a constant resisting force of 6.00 Nacts on the ball as it moves along the barrel. For the situation in part (b), at what position along the barrel does the ball have the greatest speed?

A glass bottle of soda is sealed with a screw cap. Theabsolute pressure of the carbon dioxide inside the bottle is $1.90\times {10}^{5}$ Pa. Assuming that the top and bottom surfaces of the cap eachhave an area of $3.60\times {10}^{-4}{m}^{2}$ ,obtain the magnitude of the force that the screw thread exerts onthe cap in order to keep it on the bottle. The air pressure outsidethe bottle is one atmosphere.
