Step-by-step explanation:
First, find the degrees of freedom:
df = n − 1
df = 49
To find the p-value manually, use a t-score table. Find the row corresponding to 49 degrees of freedom. Then find the α column that corresponds to a t-score of 1.421. You'll find it's between α = 0.10 (t = 1.299) and α = 0.05 (t = 1.677). Interpolating, we get an approximate p-value of 0.084. For a more accurate answer, you'll need to use a calculator.
Step-by-step explanation:
Total cards that deck contains= 5+4+2+1=12 ( as mentioned in question)
So,
1. Probability of getting blue card is 1/12
2. Probability of getting a red card is 2/12=1/6
hope it helps
