cin=input().split()
N=int(cin[0])
M=int(cin[1])


result={}
ac=0
wa=0
for i in range(M):
    cin=input().split()
    p=int(cin[0])
    S=str(cin[1])

    log=result.get(p,None)
    if S == "AC" and log != "AC":
        ac+=1
        result[p]="AC"

    if S == "WA" and log != "AC":
        wa+=1

print(f"{ac} {wa}")
