Answer:
0.0009765625
Step-by-step explanation:
Each multiple choice question has 4 equally likely alternatives.
Hence, probability of guessing the right answer for 1 question is
= 0.25
Hence, probability of guessing the wrong answer is
= 0.75
The probability of guessing 5 or more questions correctly = probability of guessing 5 questions correctly & 1 question wrong + probability of guessing 6 questions correctly
= ![\[0.25^{5}*0.75+0.25^{6}\] ](https://tex.z-dn.net/?f=%5C%5B0.25%5E%7B5%7D%2A0.75%2B0.25%5E%7B6%7D%5C%5D%0A)
= 0.000732421875 + 0.000244140625
= 0.0009765625
Step-by-step explanation:
.3f+1 = .2f-4.5
1. Subtract .2f both sides
.1f+1 = -4.5
2. Subtract 1 from both sides
.1f = -5.5
3. Divide .1 both sides
f = -55
To check plug in -55 to all the f’s and both sides should be equal.
Hope this helps!
