if the probability that the islanders will beat the rangers in a game is 0.44,what is the probability that the islanders will wi
Rama09 [41]

Answer:

30.91% probability that the islanders will win exactly one out of four games in a series against the rangers

Step-by-step explanation:

For each game, there are only two possible outcomes. Either the Islanders win, or they do not. The probability of the Islanders winning a game is independent of other games. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

The probability that the islanders will beat the rangers in a game is 0.44

This means that p = 0.44

What is the probability that the islanders will win exactly one out of four games in a series against the rangers? ​

This is P(X = 1) when n = 4. Then

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 1) = C_{4,1}.(0.44)^{1}.(0.56)^{3} = 0.3091

30.91% probability that the islanders will win exactly one out of four games in a series against the rangers

Can someone please help me I don't understand and I'm trying to learn this :((​

In a parallelogram the two angles on the same side need to equal 180 degrees. So in the picture angle F and angle G need to equal 180:

Add them together:

7x -5 + 3x-15 = 180

Simplify by combining like terms:

10x -20 = 180

Add 20 to both sides:

10x = 200

Divide both sides by 10:

X = 20

Now you know x, replace x in the angle for g and solve:

G= 7x-5 = 7(20) -5 = 140-5 = 135

G = 135 degrees.

In a parallelogram the top and bottom are the same length, so set the two to equal each other and solve for y:

3y = y + 8

Subtract y from both sides:

2y = 8

Divide both sides by 2:

Y = 4

Now replace y and solve for EF:

EF = 3y = 3(4) = 12

EF = 12

6. A vehicle covers a distance of 43.2 km in 2.4 litres of petrol. How much distance will
azamat

Answer:

18 km

Step-by-step explanation:

set up a ratio:

for 2.4 liters of petrol, 43.2 km is covered

for 1 liter of petrol, x km is covered

so 2.4/43.2 is equal to 1/x

cross multiply:

2.4x = 43.2

simplify:

x=18

the vehicle will cover 18 km in one liter of petrol
