Step-by-step explanation:
its right
The amount of possible paths to success is known as probability. the total number of outcomes that can occur.
Probability Calculation:
- Probability is the science of calculating or estimating how likely or 'probable' something will occur.
- A probability of an event occurring can be expressed using words such as "certain," "impossible," or "probable."
- Probabilities in mathematics always are expressed as fractions, decimals, or percentages with values ranging from 0 to 1.
For question 1:
Х [tex]\sim[/tex] Binomial (n, p):
[tex]\to P(x) =^n C_x \ p^x g^{n-x}[/tex]
n=3
p=0.40
[tex]\to P(x=3) =^{3} C_3 \ (0.40)^3\ (0.60)^0 = 0.064[/tex]
For question 2:
[tex]\to P(x \geq 1) = 1 -p(x=0) \\\\[/tex]
[tex]= 1- [^{3} C_0 (0.40)^0 (0.60)^3]\\\\ =0.784[/tex]
- Please find the correct question in the attached file.
