Answer:

0.675

Step-by-step explanation:

given that Ted is  taking a true-false test. He has a 90% chance of identifying the correct answer to each question. Unfortunately, there is a 25% chance that he will circle the opposite of his intended answer.

For Ted circling the correct answer  to any particular question on this test,

first he has to identify the correct answer and then round the correct answer.

Probability for Ted circles the correct answer to any particular question on this test

= Prob for idenfitying correct answer and rounding correct answer

= P(identify correct answer)*P(rounds of correct answer)

= 0.90 ( 1-0.25)

= 0.675

Will upvote<br><br> 4,7,12,19,31,... does this classify as a arithmetic, geometric, or neither
spayn [35]
To find if a series is either geometric or arithmetic:
it must satisfy this property:

Arithmetic:

a(n+1) - a(n) = const

Geometric:

a(n+1)/a(n) = const

In your case:

r1 = 7 -4 = 3

r2 = 12 - 7 = 5

r1 != r2  (not arirthmetic)

Geometric check:

r1 = 7/4

r2 = 12/7

r1 != r2  (not Geometric)

so neither.
