Answer:
0.58
Step-by-step explanation:
The first approach to solving the question above is to find the product of 0.3 and 0.4 thus:

Next step is to find the sum of 0.3 and 0.4 thus:

The final step is to find the difference between the two results. Thus:

Therefore, the product of 0.3 and 0.4 subtracted from the sum of 0.3 and 0.4 is 0.58
For this Q:
mean=31
st.dev.=0.8
x=32
Calculate z-score:
z=(x-m)/s = (32-31)/0.8=1.25
This z-score value corresponding to the probability of 0.8944
