Step-by-step explanation:
Recall that on the unit circle, each point is represented as where
. In this case, we are asked to take a loot at the interval
.
We will use the definition of tangent to solve the problem. REcall that
So, in this case, tangent is undefined whenever the denominator is zero. That is, when . Checking the unit circle with the interval
, this restriction corresponds to the upper half of the unit circle. In this case, the x component of each point is cosine. We are interested at the points where
.
. This happens only at the point (0,1), which is associated with the value of
Answer:
Probability that a customer selected at random has received either seaweed wrap or shiatsu massage is 0.33.
Step-by-step explanation:
We are given that a health spa offers holiday promotional treatment packages at a discount. Its recent tally for 4th of July holiday showed that 18% of the customers received seaweed wraps, 25% received shiatsu massages and 10% received both.
Let Probability that customers received seaweed wraps = P(SW) = 0.18
Probability that customers received shiatsu massages = P(SA) = 0.25
Probability that customers received both seaweed wraps and shiatsu massages = = 0.10
<em>Now, we have to find the probability that a customer selected at random has received either seaweed wrap or shiatsu massage.</em>
So, probability that a customer selected at random has received either seaweed wrap or shiatsu massage is given by =
<u>As we know that;</u>
So, according to our question;
= 0.18 + 0.25 - 0.10
= 0.43 - 0.10 = 0.33
Hence, probability that a customer selected at random has received either seaweed wrap or shiatsu massage is 0.33.
