Answer:

1/16

Step-by-step explanation:

multiply the separate probabilities. On the number, it's 1/8 chance you'll get 1. On the letter, it's a 3/6 or 1/2 chance you'll get an A.

1/8 * 1/2 is 1/16.

An arc on a circle measures 250°. Within which range is the radian measure of the central angle? 0 to StartFraction pi Over 2 En
Alex Ar [27]

Answer:

The central angle is within the range π to 3π/2

Step-by-step explanation:

To convert from degrees to radians, we multiply the angle in degrees by 180/π.

To convert from radians to degree, we multiply the angle in radians by 180°/π.

π/2 = π/2 X 180°/π= 90°

π rad = π X 180°/π= 180°

3π/2 = 3π/2 X 180°/π= 270°

2π = 2π X 180°/π= 360°

Therefore the angle 250 which is between 180 and 270 is within the range :

π to 3π/2

Annie writes the numbers 1 through 10 on note cards. She flips the cards over so she cannot see the number and selects three car
Kay [80]
<h2>The probability that Annie has selected the cards numbered 1, 2, and 3 is (\frac{1}{720} )</h2>

Step-by-step explanation:

Here, the total number of cards in the set = 10

The cards are numbered as 1,2,3,4,5,...., 10

P(Any event E)  = \frac{\textrm{Total favorable events}}{\textrm{Total number of events}}

P(picking a card with number 1)  = \frac{\textrm{Total cards with number 1 on it}}{\textrm{Total cards}} = (\frac{1}{10})

Now when the first card is picked, the number of cards left = 10 - 1 = 9

P(picking a card with number 2)  = \frac{\textrm{Total cards with number 2 on it}}{\textrm{Total cards}} = (\frac{1}{9})

Similarly, P(picking a card with number 3)  = \frac{\textrm{Total cards with number 3 on it}}{\textrm{Total cards}} = (\frac{1}{8})

So, the total probability  that she has selected card with number 1, 2 and 3

= (\frac{1}{10} ) \times (\frac{1}{9} ) \times (\frac{1}{8} ) = (\frac{1}{720} )

Hence,  the probability that she has selected the cards numbered 1, 2, and 3 is (\frac{1}{720} )
