Answer:

11/16

Step-by-step explanation:

P(THHH)=4!3!∗(12)4=416P

(THHH)=4!3!∗(12)4=416, we are multiplying by 4!/3! since THHH scenario can occur in number of ways: THHH, HTHH , HHTH, or HHHT (notice that 4!/3! basically gives number of arrangements of 4 letters THHH out of which 3 H's are identcal).

P(T≥2)=1−(1/16+4/16)=11/16

Write a function min that has two str parameters and returns the smallest. (Smallest in the sense of coming first alphabetically
matrenka [14]

Answer:

The function written in python is as follows

def min(str1,str2):

     if str1 < str2:

           return str1

     else:

           return str2

Step-by-step explanation:

This line defines the function min, along with two parameters str1 and str2

def min(str1,str2):

This line checks if str1 is less than str2

if str1 < str2:

If yes, the function returns str1

 return str1

If otherwise,

else:

The function returns str2

 return str2

Take for instance

str1 = "abc"

str2 = "cba"

The function will return str1 because str1 is less than str2 in the sense that the first letter of str1 (a) is less than the first letter of str2 (c)

Please help, preferably in the next half an hour.
scoundrel [369]

Answer:

For the first question the correct form would be B. It would be 6(p-3)=42. For the second question the answer would be 10.

Step-by-step explanation:

For the first question B is correct because it's 3 dollars off which would be -3.

For the second question you would multiply 6 with p and 6 with -3. This would equal to 6p-18. This would make the equation 6p-18=42. You would then add 18 to 42, which equals 60. Finally you would divide 60 by 6, which equals 10, which is your answer.
