Q. The probability that a student passes a statistics test is 2/3 and the

kenny6666 [7]

Answer:

4/9 or 44.44%

Step-by-step explanation:

We have the following probabilities:

Probability of winning the statistical test = P (s) = 2/3

Probability of winning the mathematics and statistics test = P (s n m) = 14/45

Probability of winning at least one test = P (s u m) = 4/5

We have that, the probability of winning the mathematics test P (m) can be found in the following way:

P (s n m) = P (s) + P (m) - P (s u m)

replacing we have:

14/45 = 2/3 + P (m) - 4/5

P (m) = 14/45 - 2/3 + 4/5

p (m) = 4/9 = 0.444

Which is the same as there is a 44.44% probability that I will win the math test

Answer:

${ \boxed{ \bf{formular : { \tt{n(X{ \small{U}Y) = n(X) + n(Y) - n(X{ \small{n}Y)}}}}}}} \\ n(X{ \small{n}}Y) = (200 + 300) - 400 \\ = 500 - 400 \\ { \boxed{n(X{ \small{n}}Y) = 100}} \\ \\ { \underline{ \blue{ becker \: jnr}}}$

Write the fraction or mixed number as a decimal 4/10

katovenus [111]

Fractions can be read as division. The top number (also called the numerator) is divided by the bottom number (also called the denominator).

$\frac{4}{10}$ 4 / 10 = 0.4

So, the answer is 0.4.
