Key word here, "or"...so you would add the unique probabilities of either together...
P(e)=1/2, P(>4)=3/10 (the numerator is three rather than five because 2 and 4 were already accounted for in P(e)...
P=5/10+3/10=8/10=4/5 (80%)
P=0.8

Answer:

Step-by-step explanation:
1.Convert all volumes to millilitres
(a) Chlorpheniramine
V = 100 mL
(b) Lidocaine

(c) Banana flavouring

2. Calculate the total volume
Chlorpheniramine = 100 mL
Lidocaine = 59
Banana flavouring = <u> 2.5 </u>
TOTAL = 162 mL
3. Calculate the number of doses

4. Calculate the number of days

4 times the sum of f and g: 4(f+g)
6 times g: 6g
So equation : 4(f+g) = 6g
