Answer:
Probability of getting heads on the coin and spinning 4 on the spinner =
Step-by-step explanation:
When a coin is tossed the probability to get head or tail =
=
When a spinner, divided in four sections numbered from 1 to 4 is spun the probability to get 4 on the spinner =
=
Now probability of flipping heads on the coin and spinning 4 on the spinner = Probability of getting heads on the coin × probability of spinning 4 on the spinner
=
=

hope this help you
of my handwriting is bad then sorry.
All you need to know is that:
- In the first quadrant, both coordinates are positive
- In the second quadrant, x is negative and y is positive
- In the third quadrant, both coordinates are negative
- In the fourth quadrant, x is positive and y is negative
- The sine is the y coordinate of the points on the unit circle
- The cosine is the x coordinate of the points on the unit circle
- The cotangent function is defined as the ration between the cosine and the sine of an angle.
So, if sin theta is negative and cot theta is positive, you're saying that you're looking at a point with negative y coordinate and such that
The ratio of two numbers is positive if and only if they have the same sign, so the cosine must by negative as well.
Saying that an angle has negative sine and cosine is the same as saying that the angle identifies a point on the unit circle where both x and y coordinates are negative.
So, if you look at the bullet list at the beginning, you'll see that the point is in the third quadrant.
