max2010maxim [7]

Answer:

A & B are independent events. A & C, B & C are not independent events.

Step-by-step explanation:

Independent Events are the events, whose occurrences are completely unrelated to each other.

Event A 'Red dice getting 3' & Event B 'Green die getting 4' ; are unrelated to each other. The numbers on red dice & on green dice are not dependent on each other.

Event C 'Red & Green dice numbers showing sum = 7' is dependent on the numbers coming on red & green dice , i.e events A & events B respectively. So, event C is dependent on both events A & B.

Can someone please help me with 1 to 2 please . With explanation. And how you got the answers
Neko [114]

So, the rate per 7 minutes is 7:196

To find the unit rate (how many spins per minute) we need to divide the 196 by 7.

196/7 = 28

The unit rate is 1:28

At this rate, the unicycle makes 420 revolutions per 15 minutes. We find this by 28 * 15 = 420.
