Step-by-step explanation:
Answer: 0.9738
Step-by-step explanation:
This is solved by the probability distribution formula for random variables where probability of determining random variable X is given by
P(X=r) = nCr * p^r * q^n-r
Where n = number of sample = 6
p = probability of success = 0.545
q = 1-p = 0.455
r = possible outcome from number of sample.
If 6 random births are chosen, Probability that at least 1 of them is a girl = 1 -[probability that none of them is a girl] = 1 - [probability that all 6 kids are boys]
Probability that all 6 kids are boys = 6C6 * 0.545^6 * 0.455^0 = 0.0262
Probability that at least one is a girl = 1 - 0.0262 = 0.9738.
Answer:
x = 55°
Step-by-step explanation:
Hello!
The sum of angles in a triangle is 180°.
To solve for x, we have to subtract the given angles from 180°.
<h3>Solve for x</h3>
- 180° = ∠1 + ∠2 + ∠x
- 180° = 75° + 50° + x°
- 180° - 75° - 50° = x°
- 55° = x°
The value of x is 55°.
Answer:
2,100 miles
Step-by-step explanation:
<u>Step 1-</u> Find the miles the car can travel per gallon
630 miles/ 15 gallons=42 miles per gallon
<u>Step 2-</u> Multiply the miles per gallon by the number of gallons being used
42x50=2,100 miles
