4. Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Part A: Write the probability model for this spinner. (Write probabilities as decimals, rounded to 2 decimal places.) P(Spinning 2) _
P(Spinning 3)_
P(Spinning 4)_
P(Spinning 5)_
P(Spinning 6)_
Part B: Use the probability of spinning a 6 to predict how many times Stacy would spin a 6 if she spun 50 times.
Stacy would spin 6 approximately_ times in 50 tries. ​

This will be s - r.

Step-by-step explanation:

Here,

SinB = r

CosB = s

SinB = AC/BC

Also,

CosC = AC/ BC

So, we can say SinB = CosC = r

Again,

CosB = AB/ BC

Also,

SinC = AB/ BC

So,

CosB= SinC = s

So,

SinC - CosC = s - r
