Step-by-step explanation:
The county-fair prize wheel has equally spaced sections with the following colors: 1 is golden, 2 are silver, 3 are green, 4 are blue, 6 are red, and 9 are yellow, 25 sections in total.
A. The probability of landing on gold is
or 4% as a percent.
B. If the probability of landing on yellow is 36% (or 0.36 as decimal), then the probability of not landing on yellow is
or 64% as a percent.
C. If the wheel is spun 1 time, the probabilty of landing on silver is
or 8% as a percent.
If the wheel is spun 100 times, the expected number of landing on silver is
Answer:
There is a 13.40% probability that a message is spam, given that it contains the word "text" (or "txt").
Step-by-step explanation:
The problem states that
There are 5574 messages.
There are 747 messages that are spam.
Every message contains the word text.
Bayes rule:
What is the probability of B, given that A?
In this problem, we have that
A is containing the word text. So
So
is containing the word text and being a spam message. So:
There is a 13.40% probability that a message is spam, given that it contains the word "text" (or "txt").
