Answer:

90 minutes long

1 hour, 30 minutes

Step-by-step explanation:

The science class begun 1:30pm and ends 3:00pm

An hour is 60minutes.

Between 1:30pm and 2:00pm is 30minutes.

And from 2:00pm to 3:00pm is an hour, that is 60minutes

We therefore have 30minutes+60 minutes=90 minutes long.

We can also say an hour, 30 minutes

Nataly [62]

Answer:

Hence, player A will win with probability = 5/9. Explanation has given below.

Step-by-step explanation:

Two player such as A and B chose the three spinners and contain numbered 9 , 5 and 1.

Spinner one has 3 regions = (9, 5, 1)

Spinner 2 has three regions= (3, 8, 4)

Spinner 3 has three regions = (7, 6, 2)

Let

Player A chooses one of three spinners = (9, 5, 1)

Player B chose spinner = (3, 8, 4)

Possible outcomes are = [ (9,3), (9,8), (9,4), (5,3), (5,8), (5,4), (1,3), (1,8), (1,4)]

Total possible outcomes are = 9

One with the higher number wins the game.

Player A wins = (9,3), (9,8), (9,4), (5,3), (5, 4)

Player B wins = (5, 8), (1,3), (1,8), (1,4)

Hence, player A will win with probability = 5/9.
