Aloiza [94]

Answer:

Probability of choosing one club and one spade = 0.6025

Step-by-step explanation:

Total number of cards= 52 cards

For the first event

Probability of choosing a club

Toatal club = 13 cards

Probability of choosing a club

= 13/52

Probability of choosing a club

= 1/4

Probability of choosing a club

=0.25

For the second event

Probability of choosing a spade

Toatal spade = 13 cards

Probability of choosing a spade

= 13/52

Probability of choosing spadep

= 1/4

Probability of choosing a spade = 0.25

Probability of both = 0.25*0.25

Probability of both = 0.6025

The chance of picking a almond cookie the first time:
you have 6 cookies, 3 of them are almond
So the chance of taking an almond cookie is
$\frac{3}{6} = \frac{1}{2}$
The second time there are 5 cookies left, 2 of them are almond cookies
The chance of taking an almond cookie is
$\frac{2}{5}$
To know the probability of picking two almond cookies in a row, multiply the changes:
$\frac{1}{2} \times \frac{2}{5} = \frac{1}{5}$
The chance of taking two almond cookies is 1/5

Answer:

Step-by-step explanation:

Difference between (x) & (x')

P - P' = (2 - (-6) , 2 - 2) = (-8,0)

Q - Q' = (5 - (-3), 2 - 2) = (-8,0)

etc...

Always get (-8,0) hence -8 in x-direction

12) Angle ACD= Angle ABC+ Angle CAB ====> You MAY end here
That is, Angle ACD= 132+21
            Angle ACD= 153

13) Angle ABC+ Angle BAC= Angle ACD====> You MAY end here
That is,     Angle ABC +16=143
                                   -16= -16
                Angle ABC=127
