What is the sign of the product (3) × (−3) × (−2) × (4)?
Free_Kalibri [48]

Answer:

Positive, because the products (3) × (−3) and (−2) × (4) are negative and the product of two negative numbers is positive.

Step-by-step explanation:

Since 1 * -1 = -1, and -1 * -1 = 1, the product of opposite signs produces negative numbers while the product of same signs produces positive numbers. So the product of 1 * 1 * 1 * -1 = -1, while -1 * -1 * -1 * -1 = 1.

Answer:

The required probability is 4/7.

Step-by-step explanation:

The sample space for the experiment is: { BB, BR, RB, RR }

The outcome of the event we require is: { BR, RB }

The probabilities for each outcome is given as:

BB: 3/7 x 2/6 = 1/7

BR: 3/7 x 4/6 = 2/7

RB: 4/7 x 3/6 = 2/7

RR: 4/7 x 3/6 = 2/7

Adding the probabilities we have:

{ BR, RB} = 2/7 + 2/7 = 4/7

That's it!
