Answer:

neither

A hat contains pieces of paper marked with the numbers 1 through 16. Tell whether picking an even number is impossible, unlikely
Anna [14]

Answer:

Picking an even number is an as likely event and it's probability is 1/2

Step-by-step explanation:

We know that the numbers present are 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16

The odd numbers are 1,3,5,7,9,11,13,15

The even numbers are 2,4,6,8,10,12,14,16

There are 8 even numbers and 8 odd numbers.

And also if we pick a number it should be either an even number or an odd number.

Probability(Getting an even number) = \frac{even number}{even number+oddnumber}

Probability = \frac{8}{8+8} = 1/2

Therefore picking an even number is an as likely event and it's probability is 1/2

marusya05 [52]

Answer:

1 - 2√7

( 4 + √7)(2 - √7)

Open the brackets with

( 4+ √7)

= 4( 2 - √7) + √7(2 - √7)

= 8 - 4√7 + 2√7 - √49

= 8 ( -4 + 2)√7 - √49

= 8 - 2√7 - 7

= 8 - 7 - 2√7

= 1 - 2√7
